Init implementation of IsoFileSrc. Ecma119Image, defined for first time in this commit, is the context for image written. It keeps the low level objects needed during image written. IsoFileSrc is the low level object that takes care about the info needed to write file contents to image. It takes care about reading from Stream in 2K block chunks. To prevent the same file be written twice to image, we keep in Ecma119Image a search tree, indexed by the triple key (fs, device, inode) that uniquelly identifies a source.

typedef struct ecma119_image Ecma119Image;
Initial support for low level ECMA-119 tree. This only adds the tree creation functions, no sorting and name mangling yet. Only plain ECMA-119 supported for now, nor RR, relaxed restrictions, etc.. This also adds a little test program.

typedef struct ecma119_node Ecma119Node;
Fix bug in IsoFileSrc implementation, related to a wrogn usage of tsearch. It happens that tsearch seems to not return a pointer to the inserted element, but a pointer to a pointer to the inserted element (that makes sense, as we are inserted pointers...). This bug, thus, was related to a wrong understanding of the tsearch API!
